Matthew Townsend pleaded not guilty to a felony charge of witness intimidation Thursday, according to online court records.
A three-day trial was scheduled for Sept. 28 at the Ada County Courthouse in Boise.
The 29-year-old Meridian man is accused of threatening a police officer, who in January arrested and charged Townsend with resisting and obstructing.
Prosecutors say a March 18 Facebook post by Townsend crossed the line. If convicted on the felony charge, he faces up to five years in prison and/or a $50,000 fine.
